摘　　要：为量化分析和评定肢体伤残患者康复训练后的康复程度,研究开发出一种基于三维MEMS加速度传感器的步态康复训练分析系统。通过单片机控制并由三维MEMS传感器采集患者行走时的加速度信号,将信号通过RF无线传输至计算机内,由计算机程序处理分析患者的步态信号,从而量化分析患者的康复程度,并储存患者的步态运动信息以供医生定期分析,作为今后康复治疗的依据。通过实验证明了使用加速度传感器代替传统影像学检测步态状况的可行性,相比于传统的基于影像学的步态分析系统,采用MEMS加速度传感器的步态分析系统大大减小了系统的体积和复杂性,使患者使用更加方便,便于推广应用。For quantitative analysis and evaluation of patients with limb disability after rehabilitation training, we developed a gait rehabilitation training and evaluation system based on three-dimensional MEMS acceleration sensors. Single-chip microcomputer controls the three-dimensional MEMS sensor to acquire patient＇s walking acceleration signal, sending it to the computer wirelessly via RF transmission. The computer is programed to analyze patient＇s gait data for quantitative estimation of the patient＇s recovery. The patient＇s gait movement information is stored for doctors to proceed periodical analysis, as the basis of rehabilitation therapy in the future. Experiments prove that replacing traditional imaging with acceleration sensors to detect the gait is feasible. Compared to traditional gait analysis system based on imaging, the gait analysis system combined with MEMS acceleration sensors remarkably reduces the size and complexity of the system, provides convenience for patients, and is easy for application.
